IBM CICS Transaction Server SPI command resources must be properly defined and protected.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-224735	ZCICT021	SV-224735r855162_rule		Medium

Description
IBM CICS Transaction Server can run with sensitive system privileges, and potentially can circumvent system controls. Failure to properly control access to product resources could result in the compromise of the operating system environment, and compromise the confidentiality of customer data. Many utilities assign resource controls that can be granted to system programmers only in greater than read authority. Resources are also granted to certain non systems personnel with read only authority.

Fix Text (F-26414r520308_fix)
Ensure that the IBM CICS Transaction Server command resources defined in the IBM CICS-RACF Security Guide access is in accordance with those outlined in CICS SPI Resources table in the site security plan use CICS SPI Resources table in the zOS STIG Addendum as a guide. These tables list the resources and access requirements for IBM CICS Transaction Server; ensure the following guidelines are followed: The TSS resources and/or generic equivalent as designated in the above table are owned or DEFPROT is specified for the resource class. The TSS resource access authorizations restrict access to the appropriate personnel as designated in the above table. The following commands are provided as a sample for implementing resource controls: TSS ADD(dept-acid) SPI(ASSOCIAT) TSS PERMIT(cicsaudt) SPI(ASSOCIAT) ACCESS(READ) TSS PERMIT(cicuaudt) SPI(ASSOCIAT) ACCESS(READ) TSS PERMIT(syscsaudt) SPI(ASSOCIAT) ACCESS(READ)
